BENCH VISE.

Application filed, February 27, 1922. Serial N'o. 539,616.

' longitudinal movement while they are being planed or otherwise worked upon.

Still another object-of the invention is the production of a device of this sort which is instantly adjustable to suit the work..

yThe invention has for a further object the production lof an improved carpenters vise adapted to hold work securely on top of the bench or which may be employed to hold the work firmly against the face or side of the bench.A

With these and numerous other objects in view, the invention, consisting in the construction, combination and novel `arrangement of parts, will be clearly understood from the following description, reference `being had to the accompanying drawings which form a part of this application and in which like figures of reference indicate corresponding parts throughout the several views, of whicln- Fig. 1 is a plan of a device constructed in accordance with my invention and mounted on the end of a bench, parts bei-ng cut away and shown in section.

Fig. 2 is a side elevation of the same..

Fig. 3 is a vertical section of the same taken on the line '3 of Fig. 1. j

Figpl is an end elevation of one yot the vise jaws, and

Fig. 5 is a fragmentary, vertical sectiony similar to Fig. 3 of a modification of the mounting of one of the jaws. j

IVhile I have illustrated and hereinafter described the preferred embodiment of thev invention, I would not be understood as being limited to such specific construction, for various alterations and modifications may be made in the details of construction and arrangement of parts herein disclosed without departing from the spirit and f handle-bar, 19.

scope of the invention as defined in the appended claims.

The preferred form of my device is particularly designed for mounting upon and use with the combination bench and trestle forming the subject of my co-pending application No. 539,615, filed February 27, 1922; yet it is equally as well adapted for mounting upon the usual carpenters bench or any other suitable support.

Referring, now, to the illustrations, 6 represents the end portion of a plank of a carpenters bench or other suitable support. The main supporting body of my device pre'ferably consists of an elongated block, 7, extending transversely across and abutting the end of 'the member, 6. On y'the underside of the body, 7, is a cleat, 8, suitably secured to the body, 7, as by bolts, 9, or otherwise. The cleat, 8, extends below and is secured to the member, 6, as by bolts, 10, or otherwise, andthe front edgefof the 'body is clad with a. metal strip, 11, `suitably secured to the body, 7, as by screws, 12, or otherwise, the said strip, 11, being extended to embrace the edge of the member, 6, to which it is suitably secured by screws, 13, or otherwise'. The body, 7, is so constructed and'mounted that its upper side is flush vwith the upper side of the member, 6.

I provide adjacent the face of' thel block' a screw-controlled vise-jaw, preferably comprismg a rectangular plate, 14, through which passes a bolt, 15, projecting into an opening, 16, in the body, 7, and threaded into a block, 17, embedded in 'the body. yTo the outer end of the bolt, 15, is fixed' a T- head, 18, carrying the usual vise-operating The portion of the bolt, 15, passing through the jaw, 14, is reduced to provide a shoulder, 20, engaging the inner face of the jaw. The said jaw "carries a pin, 21, which reciprocates yfreely inan opening, 22, in thebody, 7; and serves 'to prevent rotary. movement of the jaw. The jaw extends a distance above the body, the said extended portion being provided with a projection, 23, which serves as a stop for boards :or other work, as will be presently made more clear.

The jaw, 14, co-acts with a second which is carried by suitable means to slide towards its companion, and so constructed erative relation with its companion.4 The said secondjaw may comprise a bar, 24, eX- tending transversely across the body, 7, disposed longitudinally with respect to the bench and having its engaging face in substantial parallelism with the face of the jaw, 14. The said second jaw overhangs the free edge of the body, 7., and is provided with a channel, 25, slidable on a guide-bar,

26, preferably rectangular' in across section and carried between an extended portion, 27, of the cleat, 11, and an arm, 28, on the opposite end of the body, 7. The said second jaw is lalso provided with a shoulder,

I have illustrated the operation of they device by indicating in dotted lines a board, 32, 'resting upon the bench and having its endportion disposed between the jaws and abutted against the stop, 23, whereby it will be `seen that by turning the screw, 1,5, in the appropriate direction the end portion of the board will beA clamped firmly between the jaws, lateral movement of the jaw, 24'being prevented by its binding on the guide-bar, 26. .Thus it will be seen the board is held firmly against either longitudinal or lateral movement while it is being dressed.

AIt is evident the jaw, 24, may be instantly adjusted laterally by grasping its channeled end portion and sliding it in either direction yon the bar, 26, and it is also apparent that it can not be moved by lateral lpressure on its free end portion. To oppose any tendencyv of the bar, 26, to buckle under strain of thel jaw, 24, I reembrace its intermediate portion by extending the cleat, 8, and securing it to the underside of the bar, 26, as byy a machine screw, 33, or otherwise.

lIt is also apparent that when desired boards or other work may be clamped firmly against the yface of the bench by securing such work vbetween the j,aw,l14, and the cleat, 11. By mounting the jaw as shown Fig. 5, the guide member, 31, may be f dispensed with. In this construction the bar, 26, is made relatively widery than is y shown `in the Ipreviously described form,

and the jaw, 24, is provided with a T- groove, 34, to slidably support the jaw in the bar. j,

f Having thus described my invention, what I claim as new and desire to secure by Lettersv Patent of the United States, is:

1. A device of the class described including a horizontal body, a screw-controlled vise jaw movable toward and from the side thereof,l and yprojecting above the vplane thereof, a transverse guide bar spaced from the end of the body, and an elongated second jaw slidably supported .onthe bar and projecting over the surface of the body.v

2. A device of the class described comprising a horizontal body, a screw-controlled vise jaw movable toward and from the side thereof and projectingl above the plane thereof, a transverse guide bar spaced from the end of the body, and an elongated second jaw projecting over the surface of the body and having one end portion slidably mounted on the bar, said Isecond jaw being' adapted to grip the bar to prevent sliding when'lateral pressure is applied to itsprojecting portion. l

` 3. A levice of the class described including a horizontal body, a. screw-controlled vise jaw movable toward and from the side thereof and projecting above the plane thereof, a transverse guide bar spaced from the end of the body and disposed below the plane of thepsurface thereof, an kelongated second jaw having one end portion above the surface of the body and its other end portion slotted to slide upon the guide bar, a transverse strip on the body having one edge portion overhanging thel lend of the body, and a shoulder on said second rjaw slidably engaging the under side of the overhanging edge portion of said strip. 4. A device of the -class described including a horizontal body, a screw-con-v trolled vise jaw movable toward and from the side thereof and projecting above the plane thereof, a transverse guide bar spaced from the end of the body and disposed below the plane of the surface thereof, an

elongated second jaw having one end portion above the surface ofthe body andits y other end portion channeled transversely on its under side to slide on the bar, ashoulder on thesaid channeled end portionslidably vengaging' the under 'side of the bar, a'transverse strip on'- the bodyhavin'g one edge portion overhanging the end ofthe body, and a shoulderI on the said second jaw slidably `engaging the under side of the overhanging edge portion of said strip.

In testimony whereof,"'I have lhereunto s et my handthis 11 day of February, 1922.
